The temperature difference between the Southern Great Plains and the ocean produces winds that carry moisture from the Gulf of Mexico to the Great Plains, fueling more intense storms as the climate warms.

Six PNNL researchers named to the list of the most highly cited in the world. The list features scientists from around the world whose citations rank in the top one percent within 22 subject areas.

PNNL tools that track underground contaminants and speed carbon capture technology development are among R&D Magazine's 100 most innovative scientific breakthroughs of the year.

Nuclear power figures prominently in our country's energy portfolio and is essential to our economic and environmental security.

In fast-neutron reactors, fuel is sealed in ~7 millimeter diameter steel tubes called cladding. When a high-energy "fast" neutron strikes an atom in the steel, it can knock the atom out of place, like a cue ball striking another billiard ball. This leaves two types of damage in the metal: an empty spot where the atom was, and the displaced atom wedged between other atoms. Over time, these defects typically drive undesirable rearrangement of the microstructure, potentially reducing the life of the cladding.

Discovery in action. These words describe what we do at PNNL. For more than 50 years, we have advanced the frontiers of science and engineering in the service of our nation and the the world.

PNNL takes pride in advancing scientific frontiers and developing solutions to vexing problems. In particular, we apply our technical expertise to address national needs in security, energy and the environment.

Calcium carbonate found in chalk, shells and rocks is one of the most important materials on earth. New insights on how it turns into hard, strong materials will help scientists design materials needed for a low-carbon future.

On October 22, the U.S. Nuclear Regulatory Commission (NRC)​​​​​​​granted Tennessee Valley Authority's (TVA's) Watts Bar Nuclear Generating Station a 40-year operating license for its new Unit 2 reactor. This is the first nuclear reactor to be granted an operating license by the NRC in two decades.
